I am in the need to replace two of my ignition coils and i wonder if there's any decent performance replacement for a 4.7 magnum. I've been looking at the MSD catalog and although there is no product for my application, the coil over plug units they sell for the 2002 to 2005 HEMI looks very similar to the 4.7 coils. Did anyone ever tried them on a 4.7lt? Did they work? Is there any other performance coils in the market that fits on a 4.7lt?
